x2-6x+9 = (x-3)(x-3) when factorised.
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
(x - 3)(x - 3)
(X-9)2
(x - 7)(x - 9)
(x+1)(x+9)
x2-6x+9 = (x-3)(x-3) when factorised.
(x-9)(x+9)
x2 + 13x + 36 = (x + 9)(x + 4)
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
(x + 4)(x + 9)
(x + 3)(x + 3)
x - 3
x2 - 14x + 45 = (x - 5)(x - 9).
(x+3)(x+3)
x - 4. x^2 + 5x - 36 = (x - 4) (x + 9) x^2 - 9x + 20 = (x - 4) (x - 5)
